HI Bill. I did brush on a few coats, but they may have been too few. Maybe I should have used more filler on the damn stuff. Any way, I removed the carbon and went back to silk span on the part that gave me fits.
The pinholes in the dope or paint over carbon fiber (presuming you brushed it as Bill indicated) are probably the result of the sizing that holds the fibers together. There are at least two types of the very light carbon mat, one looks very uniform and smooth, the other very uneven and kind of clumpy. The latter is the kind you want, the former has a lot of sizing which is incompatible with the dope.
I had a lot of problems with pinholes on my second Infinity which were not entirely solved, and it looked terrible in spots. This was using the "uniform" carbon. After researching the issue for a while, the same sort of problem seems to happen with fiberglass parts on pylon racers (also judged for appearance, or at least they were at the times). Their solution was to put on a skim coat of polyester filler - Bondo or HobbyPoxy PFC - work it into the holes, then sand it off smooth. If you wait until the primer is applied, there are only a few of them left, so the net weight increase is negligible, and the Bondo will be stable with any of the subsequent overcoats, and tiny red dots will easily disappear with the color.
